Two types of small-aspect-ratio slot jets were investigated. An orifice slot jet with a 3:1 aspect ratio was shown to have features similar to an elliptic jet with a well-designed contraction. A larger spreading rate and enhanced turbulent mixing, relative to a circular jet, can be obtained...

The phase relationship between droplet cutoff and stimulation of a continuous jet can be determined by pulsing the charging voltage during a time considerably shorter than droplet formation period. The resulting charging current varies depending on when the pulse is applied in relation to...

The existence of organized large-scale structure in jet flows has been studied using planar imaging of the CH[SUB4] concentration in a turbulent CH[SUB4] jet. The measurements show the development of large-scale vertical structures in the mixing region adjacent to the central jet. These...

The relation between mean square values of the time derivative ?[SUB,t]( =d?/dt) and the spatial derivatives ?[SUB,i( =d?/dx; i=1, 2, 3) of the temperature fluctuation ?, obtained with the assumptions of homogeneity and independence between small scales and large scales, is experimentally...

Studies four round turbulent jets of hydrogen-nitrogen mixtures discharging into slow air coflow. Mean and fluctuation of the velocity components; Radial profiles of mean density; Investigation of self-similar behavior by using a local effective jet diameter that accounts for the strong density...

Examines the structure of baroclinic waves and zonal jets in an internally heated, rotating, cylinder of fluid. Presence of a radial depth gradient; Effect of endwall configurations on the fluid depth; Observation on the baroclinic eddy features; Radial scale of the multiple zonal jets.
